WE PROPOSE THE EXTENSION OF A NEW ANALYTICAL TECHNIQUE, SPUTTER INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS) TO INCLUDE DEPTH PROFILING. THIS PHASE I PROJECT WILL DETERMINE THE FEASIBILTY OF MAKING THIS PRELIMINARY MEASUREMENTS USING THE SIRIS TECHNIQUE ON STANDARD SAMPLES OF SI DOPED ALGAAS AND TI DOPED LINBO3. SUCH SAMPLES ARE OF INTEREST TO THE AIR FORCE'S VHSIC AND ELECTRO-0PTIC DEVELOP ...

A MODIFICATION OF THE ACTIVATED SLUDGE PROCESS HAS BEEN DEVELOPED TO ELIMINATE SLUDGE BULKING, MINIMIZE REACTOR VOLUMES, AND ENHANCE NUTRIENT REMOVALS. THE FLOW SHEET UTILIZES TWO SEGMENTS IN SERIES. THE FIRST EMPLOYS A 10 MINUTE MIXED LIQUOR CONTACTOR TO ADSORB 50-60% OF THE SOLUBLE CARBON SUBSTRATE. CONTACTOR MIXED LIQUOR IS FLOTATION SEPARATED AND DISCHARGED TO A SEPARATE AERATION REACTOR FOR M ...

THE PROJECT WILL INVOLVE ADPTATION OF THE LOOP CURRENT STEP RESPONSE METHOD INVENTED AND DEVELOPED BY THE PROJECT PARTICIPANTS FOR DETERMINING INSTALLED THERMOCOUPLE RESPONSE FOR TYPE J, K AND E THERMOCOUPLES USED IN TURBINE ENGINE TEST FACILITIES. THE METHOD INVOLVES PROCESSING DATA FROM A COOLING TRANSIENT FOLLOWING CESSATION OF JOULE AND/OR PELTIER HEATING OF THE THERMOCOUPLE. THE PROJECT WILL ...

THE VLSI AND VHISC DEVELOPMENT PROGRAMS OF THE AIR FORCE REQUIRE CHARACTERIZATION OF III-V COMPOUNDS WITH AN INTERFERENCE FREE, HIGHLY SENSITIVE ELEMENT ANALYSIS TECHNIQUE HAVING GOOD LATERAL AND DEPTH RESOLUTION. SPUTTER INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS), AN ULTRASENSITIVE ANALYTICAL TECHNIQUE DEVELOPED BY ATOM SCIENCES, HAS BEEN DEMONSTRATED IN SILICON TO HAVE GOOD SENSITIVITY ...

THE REMEDIATION OF CONTAMINATED SOILS AND GROUNDS TO ENSURE PROTECTION OF PUBLIC HEALTH AND THE ENVIRONMENT IS DIFFICULTAND COSTLY. THERE IS A CRITICAL NEED FOR THE DEVELOPMENT OFTECHNOLOGIES WHICH ARE BOTH TECHNICALLY SOUND AND COST- EFFECTIVE. THE POTENTIAL REMOVAL OF ROGANIC CHEMICALS FROM UNSATURATED SOILS VIA VAPOR PHASE TRANSPORT APPEARS TO SHOW GREAT PROMISE. THIS APPROACH HAS APPLICABILITY ...

A SYSTEM IS PROPOSED FOR UTILIZING EXPERT KNOWLEDGE TO AUTOMATICALLY GENERATE DECISION TREES WITH APPLICATIONS IN TARGET DETECTION AND CLASSIFICATION. THE PROPOSED WORK REPRESENTS THE FIRST FORMALIZED ATTEMPT TO COMBINE EXPERT SYSTEM TECHNOLOGY AND AUTONOMOUS DECISION MAKING FOR TASKS SUCH AS COMPUTER VISION, PATTERN RECOGNITION, AND INTELLIGENT CONTROL. IN THE PROPOSED SYSTEM, A KNOWLEDGE BASE CO ...

A SYSTEM IS PROPOSED FOR THE UTILIZATION OF EXPERT KNOW- KNOWLEDGE TO GENERATE HIGHLY EFFICIENT SOLUTIONS TO DECISIONMAKING PROBLEMS. STARTING FROM EITHER A PRODUCTION RULE OR A DECISION TREE REPRESENTATION OF THE PROBLEM, AS SUPPLIED BY A SYSTEM DESIGNER, THE EXPERT DECISION TREE GENERATOR SYSTEM CAN PRODUCE AN EFFICIENT DECISION TREE REPRESENTATION THE USER CAN THEN EXPLORE SOME OF THE POSSIBLE ...

A PORTABLE INSTRUMENT, BASED ON THE PRINCIPLES OF X-RAY DIFFRACTION, IS PROPOSED WHICH WILL ALLOW QUANTITATIVE DETERMINATION OF THE PRESENCE OF ASBESTOS IN MATERIALS OF CONSTRUCTION. PRELIMINARY TESTS SHOW THAT A RESOLUTION OF A FEW WEIGHT PERCENT ASBESTOS CAN BE EASILY MEASURED. ANALYSISOF THE SYSTEM X-RAY PHYSICS INDICATE A LOWER LEVEL OF DETECTABILITY OF A FEW TENTHS OF A PERCENT SHOULD BE ACHI ...

THE ABILITY TO SEE THREE-DIMENSIONAL IMAGES IN CONVEYED BY ONLY A FEW TECHNOLOGIES. HOLOGRAPHY IS ONE. THIS PROPOSAL IS FOR A DYNAMIC (RECORDER OR REAL-TIME) MULTIPLEXED HOLOGRAPHIC SYSTEM IN WHICH A REMOTE LARGE-SCALE OBJECT OR SCENE-AIRCRAFT, TERRAIN OR OTHER - IS DISPLAY IN REAL TIME BY MEANS OF HOLOGRAPHY. THE MECHANISM USED IS HIGH-SPEED VIDEO RECORDING, COMBINED WITH COMPUTER AND OPTICAL TRA ...

THE MISSION OF THIS PHASE I PROJECT IS COMPLETION OF A TRULY INNOVATIVE STUDY TO UPGRADE EXISTING PNS CODES FOR COMPUTING HIGHSPEED, THREE-DIMENSIONAL RE-ENTRY FLOWFIELDS. THE PLAN OF ACTION ENCOMPASSES A THOROUGH EXAMINATION OF THE RANGE OF ADMISSABLE CFD THEORIES, TO UNEQUIVACALLY COMPARE STRONG AND WEAK POINTS FOR APPLICATION TO THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS WITH DIFFERENTIAL EQ ...
